Each of the electrode terminals BC2 is provided at any place of the cell body BC1 while being exposed to the outside, and one of the electrode terminals BC2 serves as a positive electrode and the other serves as a negative electrode. Each of the electrode terminals BC2 may be, for example, a plate-like member provided on the outer wall surface of the cell body BC1 or a columnar pole pillar protruding from the outer wall surface of the cell body BC1. In addition, when the cell body BC1 has a plurality of outer wall surfaces, each electrode terminal BC2 may be arranged on one of the outer wall surfaces, or may be arranged on a different outer wall surface.

In the battery module BM, a plurality of battery cells BC having positive and negative electrode terminals BC2 are arranged in one direction. In this battery module BM, each battery cell BC is arranged in a state where one electrode terminal BC2 and the other electrode terminal BC2 of each battery cell BC are arranged in a line. Therefore, in this battery module BM, the electrode terminal group BC5 including the plurality of electrode terminals BC2 arranged in a line is provided at two locations (FIG. 10). In the following, when there is no particular reference and the term “arrangement direction” is used, it means the arrangement direction of the plurality of battery cells BC and the arrangement direction of the plurality of electrode terminals BC2 for each electrode terminal group BC5.
